Issue: #26123
This changes the way lines in CTestCostData.txt are parsed to allow for
spaces in the test name.
It does so by looking for space characters from the end; and once two
have been found, assumes everything from the beginning up to that
second-to-last-space is the test name.
Additionally, parsing the file should be much more efficient since there
is no string or vector heap allocation per line. The std::string used by
the parse function to convert the int and float should be within most
standard libraries' small string optimization.

When profiling Qt builds on macos, about 2.2% of a `cmake` invocation
was spent reading from `/dev/urandom`. Use a (thread)local rng to
mitigate this cost, particularly in `cmGeneratedFileStreamBase::Open`.
Refactoring in commit 5ff0b4ed57 (cmCTestMultiProcessHandler:
Consolidate test readiness checks, 2023-10-20, v3.29.0-rc1~378^2~4)
accidentally broke `RESOURCE_LOCK`. Fix it and replace the previous
test with one that would have caught this.
Fixes: #25843
Under job server integration, added by commit 80fe56c481 (ctest: Add
support for running under a make job server on POSIX systems,
2023-11-15, v3.29.0-rc1~324^2), use a very high default so that
parallelism is effectively limited only by available job server tokens.
Otherwise, choose a default limit based on the number of processors.
Also allow passing `0` to specify unbounded parallelism.
Fixes: #25739
Once a test is ready to run, count it against the number of tests to
start in the current batch whether or not the test process actually
starts successfully. If a test process does fail to start, simply
schedule a new startup batch on the next loop iteration.
When a test finishes, defer starting new tests until the next loop
iteration. That way, if multiple tests finish in a single loop
iteration, we can free all of their resources first, and then start
a new batch of tests.
The `TestRunningMap` and `TestFinishMap` members have not been used
since commit 44017a4767 (CTest: handle dependent and non dependent test
requirements equally, 2013-10-17, v3.0.0-rc1~451^2~7).
It is only needed for libuv < 1.19, but since commit c050d6a01e
(string(TIMESTAMP): add %f specifier for microseconds, 2022-01-27,
v3.23.0-rc1~59^2) we require libuv >= 1.28.
This function was being called when TotalNumberOfTests hadn't been
initialized, resulting in undefined output. It's not clear why this
was never apparent until now. Accept a total argument to ensure it's
initialized.
A test process may timeout either because the test timeout was reached,
or the overall stop time was reached. Shorten the lifetime for which
we track this state in `cmCTestRunTest`.
